Title: Oil return method of heat pump system using multi compressors
Inventor: CHOI CHANG MIN
IPC: F25B31/00
Filed: 2002-07-03
Abstract: PURPOSE: A method for returning oil of a heat pump system with a plurality of compressors is provided to prevent damage of the compressors due to inferior lubrication by preventing oil level of the stopped compressor from falling down when some of the compressors are selectively operated depending on heating or cooling load. CONSTITUTION: A method comprises the steps of: a first step(S1,S2) in which some of compressors are selectively operated for a first set time depending on heating or cooling load; a second step(S3,S4) in which the compressors stopped in the first step are operated for a second set time after the first set time of the first step has passed; and a third step(S5) in which the compressors working for the second set time in the second step are stopped. Oil level in the stopped compressor is dropped down as the oil in the compressor flows out to a refrigerant suction tube due to high pressure in the compressor. The stopped compressor is operated for the second set time to return pressure in the compressor to restore the oil level.
